Now-a-days, manufacturing industry is facing new challenges with the rapidly growing markets and quickly increasing needs. Thus, the traditional design process should be reformed. In the actual design process, designers often encounter difficulties in searching and reusing the design information. With the development of manufacturing industry, the traditional product design process requires more rapid and intelligent information database system. In this paper, an agent oriented active database system is proposed, which have the characteristic of distributed, initiative, and intelligent. Furthermore, the retrieval algorithm is designed to calculate the similarity between parts.
